How to decode a base64 encoded string to byte array on Android API level 7?
Can it be done using any standard packages of Java?
Should i copy the source code from google search results?
Should i re-implement encoder and decoder according to RFC?
API level 8 has util package android.util.Base64 that does this, but i have to do development based on API level 7.

I'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

There seems to be a problem with an uncaught exception and reflection, although....why does it work on API level 10?
I know it is not right to do this, but is there any APK decoder/decompiler available around?

D/skia (374): --- decoder->decode returned false
I need to use Base64.decodeBase64 in my application, I had to download and include it myself into my project from apache commons.
Why is this not included in the default Android base system? Are there some weird licensing issues with this function or is it hidden somewhere else under a different name?
For my current application I collect images from different "event providers" in Spain.
However, when downloading images from salir.com I get the following logcat output: 13970 Gallery_Activity
I Fetching image 2/8 URL: http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortale... 13970 ServiceHttpRequest
I Image [url] fetched in [146ms] 13970 skia D --- decoder->decode returned false
Searching for that error message didn't provide much useful results.
Is it now possible mit sdk1.6 the audio decoder to access/use without using MediaPlayer ?
I saw : New version of OpenCore
Android 1.6 includes the updated OpenCore 2 media engine, which has:
* Support for OpenMAX encoders* Support for additional audio codecs in AuthorEngine* Improved buffering model supports shared buffers allocated in the decoder. but dont know how!
I am trying to open a remote Stream of a JPEG image and convert it into a Bitmap object code...
The decoder returns null and in the logs I get the following message:
DEBUG/skia(xxxx): --- decoder->decode returned false
Note:
1. the content length is non-zero and content type is image/jpeg
2. When I open the URL in browser I can see the image.
What is that I am missing here?
I want to convert a image into Base64 format and send it to server. I have one Base64 class which accept byte array and return a string.I am sending image into chunks of data.I am creating creating one chunk of 100kb. If image is less than 100 kb then image is uploaded on server, but if it is greater than 100kb (i.e when it requires more than one chunk) then it will not uploaded. I think it is because I am converting image into Base64 in parts and on server it decode it only in one shot. Now I want to send a image for conversion of Base64 only in one chunk. But if image is too large then it throw OutOfMemoryException (Obviously after all it is mobile having very limeted resources).
My code is as follows:

I have public key as a base64 encoded string (126 characters), How do i create 'PublicKey' with the encoded string and use it with Cipher.
In the app I am making, I would like to take a Base64 image that is received from a server, and save it to a file for displaying later. My question is where should I store this file? It needs to be dynamic, and may be empty when the program launches. I am unsure how exactly the file system on Android works, such as how file paths look.
Ideally I would like to be able to write the data to the image file using a FileOutputStream, and then display that image somehow.
In an android application we are receiving a byte64 string.I need to convert these strings to images.

View 2 Replies View RelatedI have updated my tools to revision 7 and now I can't do a build as it says the API level is obsolete. I can understand warning but it won't build at all. I am using android.bat to generate a build.xml for release versions. So the build.xml gets made from scratch each time. If I switch to --target 8 it builds but I have already released it on the Android Market with 6. Won't this mean that some people that have Android 2.0.1 won't be able to run it?

I'm looking for some way in Android to play in-memory audio in a manner analogous to the waveOutOpen family of methods in Windows programming. The waveOut... methods essentially let an application create arrays of sample values (like in-memory WAV files without the headers) and dump them into a queue for sequential playback. Windows transitions seamlessly from one array to the next, so as long as the application keeps dumping arrays into the queue ahead of playback, the program can create and play continuous audio of any arbitrary length. The Windows API also incorporates a callback mechanism that the application can use to indicate progress and load additional buffers.
As far as I can tell, the Android audio API lets an application play a file from local storage or a URL, or from a memory stream. Is there any way to get Android to "queue up" MediaPlayer.start() calls so that one player transitions (without glitches) into the next upon play completion? It appears that Jet does something like this, but only with its own internal synthesis engine. Is there any other way of accessing Android audio in a waveOutOpen way?
I know about LocationManagerService, AlarmManagerService, and BatteryService, from Android programming books, but is there a published list of all available services?

Is there a way to do this?
